Target Audience

This workflow is designed for:
- Data Analysts: Those who need to extract and analyze data from websites efficiently.
- Web Developers: Developers looking to automate data collection for testing or monitoring purposes.
- SEO Specialists: Professionals aiming to gather website metrics, backlinks, or competitor analysis data.
- Researchers: Individuals needing to scrape data from various sources for academic or market research.
- Business Analysts: Analysts who require insights from web data to inform business decisions.

Problem Solved

This workflow addresses the challenge of automated web scraping by providing a robust solution to collect data from any webpage, whether it requires login or not. It effectively handles session management, cookie injection, and data extraction, ensuring that users can gather relevant information without manual intervention. Additionally, it mitigates the risk of being blocked by employing techniques to clean browser traces and manage Selenium sessions.

Workflow Steps

  • Webhook Trigger: The process starts when a POST request is sent to the webhook endpoint, containing the subject and target URL.
    2. Field Editing: The workflow extracts and assigns relevant fields such as the subject and website domain for further processing.
    3. Google Search Query: If no target URL is provided, the workflow constructs a Google search query to find relevant URLs related to the subject.
    4. Selenium Session Creation: A Selenium session is initiated to allow automated browsing.
    5. Cookie Injection: If session cookies are provided, they are injected into the Selenium session to maintain user authentication.
    6. Page Navigation: The workflow navigates to the specified URL or the first relevant URL found via Google search.
    7. Screenshot Capture: The workflow captures screenshots of the webpage for visual data collection.
    8. Data Extraction: The captured screenshots are analyzed using OpenAI's language model to extract relevant information based on the subject.
    9. Response Handling: Depending on the outcome of the extraction, the workflow responds to the webhook with either success or error messages, including extracted data or relevant error descriptions.
    10. Session Management: Finally, the Selenium session is cleaned up and deleted to avoid resource leaks.

    • Customization Guide

    To customize this workflow:
    - Modify Webhook Data: Change the structure of the incoming JSON data to fit your data extraction needs.
    - Adjust Google Search Query: Update the search query parameters to target specific keywords or domains.
    - Change Extraction Logic: Modify the extraction logic in the Information Extractor nodes to fit the specific data attributes you want.
    - Session Management: Tweak the Selenium session parameters (like browser settings or session timeout) based on your scraping requirements.
    - Error Handling: Enhance error handling mechanisms to better capture and respond to specific issues that may arise during scraping.
